There is recent evidence showing that obesity is associated with gastroesophageal reflux disease and esophageal dysmotility, although symptoms are not always present.
This is a prospective study based on high-resolution manometry findings in bariatric surgery candidates and their correlation with postoperative dysphagia.
Manometric evaluation was performed on candidates for bariatric surgery from 2022 to 2024. The examination was conducted according to the protocol of the fourth version of the Chicago Classification, including different positions and provocative maneuvers to confirm the diagnosis of dysmotility. Patients were followed for 90 days after surgery to verify the occurrence of dysphagia or difficulty adapting to the diet.
High-resolution manometry was performed on 46 candidates for bariatric surgery with a mean body mass index of 46.5 kg/m2. Esophagogastric junction outflow obstruction was diagnosed in 16 (34.8%) patients, and ineffective esophageal motility was diagnosed in 8 (17.4%) patients. None of the subjects reported symptoms during the preoperative period. Out of the 46 individuals initially included, 44 underwent bariatric surgery, 23 (52.3%) underwent Roux-en-Y gastric bypass, and 21 (47.7%) underwent sleeve gastrectomy. One patient with esophagogastric junction outflow obstruction reported dysphagia after Roux-en-Y bypass, but symptoms spontaneously resolved during the 90-day follow-up period.
Although patients with severe obesity have a high prevalence of esophageal motility disorders, no clinical repercussions were observed after bariatric surgery during the study period.
